4.05. Consents

      (a) If there are any Material Consents that have not yet been obtained (or
otherwise are not in full force and effect) as of the Closing, in the case of
each Seller Contract as to which such Material Consents were not obtained (or
otherwise are not in full force and effect) (the "Restricted Material
Contracts"), Buyers may waive the closing conditions as to any such Material
Consent and either:

            (i) elect to have Seller continue its efforts to obtain the Material
Consents; or

            (ii) elect to have Seller retain that Restricted Material Contract
and all Liabilities arising therefrom or relating thereto.

      If Buyers elects to have Seller continue its efforts to obtain any
Material Consents and the Closing occurs, then notwithstanding Sections 2.01 and
2.03 neither this Agreement nor the Assignment and Assumption Agreement nor any
other document related to the consummation of the Contemplated Transactions
shall constitute a sale, assignment, assumption, transfer, conveyance or
delivery or an attempted sale, assignment, assumption, transfer, conveyance or
delivery of the Restricted Material Contracts; and following the Closing, the
parties shall use Best Efforts, and cooperate with each other, to obtain the
Material Consent relating to each Restricted Material Contract as quickly as
practicable. Pending the obtaining of such Material Consents relating to any
Restricted Material Contract, the parties shall cooperate with each other in any
reasonable and lawful arrangements designed to provide to Buyers the benefits of
use of the Restricted Material Contract for its term (or any right or benefit
arising thereunder, including the enforcement for the benefit of Buyers of any
and all rights of Seller against a third party thereunder). Once a Material
Consent for the sale, assignment, assumption, transfer, conveyance and delivery
of a Restricted Material Contract is obtained, Seller promptly shall assign,
transfer, convey and deliver such Restricted Material Contract to Buyers, and
Buyers shall assume the obligations under such Restricted Material Contract
assigned to Buyers from and after the date of assignment to Buyers pursuant to a
special-purpose assignment and assumption agreement substantially similar in
terms to those of the Assignment and Assumption Agreement (which special-purpose
agreement the parties shall prepare, execute and deliver in good faith at the
time of such transfer, all at no additional cost to Buyers).

      (b) If there are any Consents not listed on Exhibit C necessary for the
assignment and transfer of any the Seller Contracts to Buyers (the "Nonmaterial
Consents") which have not yet been obtained (or otherwise are not in full force
and effect) as of the Closing, Buyers shall elect at the Closing, in the case of
each of the Seller Contracts as to which such Nonmaterial Consents were not
obtained (or otherwise are not in full force and effect) (the "Restricted
Nonmaterial Contracts"), whether to:

            (i) accept the assignment of such Restricted Nonmaterial Contract,
in which case, as between Buyers and Seller, such Restricted Nonmaterial
Contract shall, to the maximum extent practicable and notwithstanding the
failure to obtain the applicable Nonmaterial Consent, be transferred at the
Closing pursuant to the Assignment and Assumption Agreement as elsewhere
provided under this Agreement; or

            (ii) reject the assignment of such Restricted Nonmaterial Contract,
in which case, notwithstanding Sections 2.01 and 2.03, (A) neither this
Agreement nor the Assignment and Assumption Agreement nor any other


--------------------------------------------------------------------------------
                                       17

document related to the consummation of the Contemplated Transactions shall
constitute a sale, assignment, assumption, conveyance or delivery or an
attempted sale, assignment, assumption, transfer, conveyance or delivery of such
Restricted Nonmaterial Contract, and (B) Seller shall retain such Restricted
Nonmaterial Contract and all Liabilities arising therefrom or relating thereto.

qualification.

occupy any Real Property pursuant to a Ground Lease.

      (b) Schedule 5.07 contains an accurate description (by location, name of
lessor, date of Lease and term expiry date) of all Space Leases and the street
address of all Facilities occupied pursuant to Space Leases.

      (c) With respect to parcels of Real Property which are leased by Seller
pursuant to Space Leases, Seller is currently in possession thereof and has a
valid leasehold interest therein in accordance with the terms of the controlling
Space Lease, except those described on Schedule 5.07 ("Real Estate Encumbrances"
and, together with the Permitted Non-Real Estate Encumbrances, "Permitted
Encumbrances"). In addition, all Space Leases to which Seller is a party are

operating condition, ordinary wear and tear excepted, is suitable for immediate
use in the Ordinary Course of Business and is free from latent and patent
defects. No item of Tangible Personal Property is in need of repair or

5.10. Inventories

      All items included in the Inventories consist of a quality and quantity
usable and, with respect to finished goods, saleable, in the Ordinary Course of

filed pursuant to applicable Laws. All Tax Returns and reports filed by Seller
are true, correct and complete. Seller has paid, or made provision for the
payment of, all Taxes shown on the Tax Returns as owing, except where the
failure to file Tax Returns or to pay Taxes would not have a material adverse
effect on the financial condition of the Seller. Seller currently is not the
beneficiary of any extension of time within which to file any Tax Return. There
are no Encumbrances on any of the Assets that arose in connection with any
failure (or alleged failure) to pay any Tax, and Seller has no Knowledge of any
basis for assertion of any claims attributable to Taxes which, if adversely
determined, would result in any such Encumbrance.

1.1502-6 (or any similar provision of state, local or foreign law), as a
transferee or successor by contract or otherwise.

      (d) Seller is an S corporation as defined in Section 1361 of the Code.

5.13. No Material Adverse Change

      Since the date of the Interim Balance Sheet, there has not been any

of operations or condition (financial or other) of Seller, and no event has
occurred or circumstance exists that may result in such a material adverse
change.

5.14. Employee Benefits

      Neither the Seller nor any ERISA Affiliate has ever maintained, sponsored,
contributed to or incurred any liability under any Plan subject to Section 412
of the Code or Title IV of ERISA. Neither the Seller nor any ERISA Affiliate has
ever incurred any obligation to contribute to or any liability under any
"multi-employer plan" within the meaning of Section 4001(a)(3) of ERISA or ever
participated in any "multiple employer plan" within the meaning of Section
413(c) of the Code. The written terms of each Plan are, and the Plans have been
administered, in compliance with the requirements of ERISA, and, where
applicable, Section 401 of the Code. There are not now, nor have there been, any
transactions involving any Plan which are prohibited under ERISA or the Code. As
of the


--------------------------------------------------------------------------------
                                       21
<PAGE>

Agreement Date, there are no pending or threatened claims by or on behalf of any
Plan or by any employee of the Seller alleging a breach or breaches of fiduciary
duties or violations of other applicable state or federal law which could result
in liability on the part of the Seller or any Plan under ERISA or any other law,
nor is there any basis for such a claim. All returns, reports, disclosure
statements and premium payments required to be made under ERISA and the Code
with respect to any Plan have been timely filed or delivered. Each Plan that is
intended to be qualified under Section 401(a) of the Code has received a
determination letter from the Internal Revenue Service covering all amendments
required to be adopted to date, and there are no circumstances which exist that
are reasonably likely to adversely affect the tax-qualified status of such Plan
or result in the revocation of such letter. The Seller and each ERISA Affiliate
have made all contributions and payments required to be made to each of its Plan
within the time prescribed by law or, if earlier, the terms of the Plan.

Section 8.01.

8.02. Notification

      Between the Agreement Date and the Closing, CTI promptly shall notify

or constitutes a Breach of any of Buyers' representations and warranties made as

the time of the occurrence of, or CTI's discovery of, such fact or condition.
During the same period, CTI also promptly shall notify Seller of the occurrence

9.01. Employment of Active Employees by Buyers.

      (a) Buyers are not obligated to hire any Active Employee but may interview
all Active Employees. Buyers will provide Seller with a list of Active Employees
to whom Buyers have made an offer of employment that has been accepted to be
effective on the Closing Date (the "Hired Active Employees"). Subject to Laws,
Buyers will


--------------------------------------------------------------------------------
                                       36
<PAGE>

have reasonable access to the Facilities and personnel Records (including
performance appraisals, disciplinary actions, grievances and medical Records) of
Seller for the purpose of preparing for and conducting employment interviews
with all Active Employees and will conduct the interviews as expeditiously as
possible prior to the Closing Date. Access will be provided by Seller upon
reasonable prior notice during normal business hours. Effective immediately
before the Closing, Seller will terminate the employment of all of its Hired
Active Employees.

      (b) Neither Seller nor its Related Persons shall solicit the continued
employment of any Active Employee (unless and until Buyers have informed Seller
in writing that the particular Active Employee will not receive any employment
offer from Buyers) or the employment of any Hired Active Employee after the
Closing. Buyers shall inform Seller promptly of the identities of those Active
Employees to whom it will not make employment offers.

      (c) It is understood and agreed that (i) Buyers' expressed intention to
extend offers of employment as set forth in this section shall not constitute
any commitment, Contract or understanding (expressed or implied) of any
obligation on the part of Buyers to a post-Closing employment relationship of
any fixed term or duration or upon any terms or conditions other than those that
Buyers may establish pursuant to individual offers of employment; and (ii)
employment offered by Buyers is "at will" and may be terminated by Buyers or by
an employee at any time for any reason (subject to any written commitments to
the contrary made by Buyers or an employee and Laws). Nothing in this Agreement
shall be deemed to prevent or restrict in any way the right of Buyers to
terminate, reassign, promote or demote any of the Hired Active Employees after
the Closing or to change adversely or favorably the title, powers, duties,
responsibilities, functions, locations, salaries, other compensation or terms or
conditions of employment of such employees.

9.02. Salaries and Benefits

      (a) Seller shall be responsible for (i) the payment of all wages and other
remuneration due to Active Employees with respect to their services as employees
of Seller through the close of business on the Closing Date, including pro rata
bonus payments and all vacation pay earned prior to the Closing Date; (ii) the
payment of any termination or severance payments and the provision of health
plan continuation coverage in accordance with the requirements of COBRA and
Sections 601 through 608 of ERISA; and (iii) any and all payments to employees
required under the WARN Act.

      (b) Seller shall be liable for any claims made or incurred by Active
Employees and their beneficiaries through the Closing Date under the Employee
Plans. For purposes of the immediately preceding sentence, a charge will be
deemed incurred, in the case of hospital, medical or dental benefits, when the
services that are the subject of the charge are performed and, in the case of
other benefits (such as disability or life insurance), when an event has
occurred or when a condition has been diagnosed that entitles the employee to
the benefit.

9.03. Seller's Retirement and Savings Plans

      (a) All Hired Active Employees who are participants in Seller's retirement
plans shall retain their accrued benefits under Seller's retirement plans as of
the Closing Date, and Seller (or Seller's retirement plans) shall retain sole
liability for the payment of such benefits as and when such Hired Active
Employees become eligible therefor under such plans. All Hired Active Employees
shall become fully vested in their accrued benefits under Seller's retirement
plans as of the Closing Date, and Seller will so amend such plans if necessary
to achieve this result.

      (b) Seller will cause its savings plan to be amended in order to provide
that the Hired Active Employees shall be fully vested in their accounts under
such plan as of the Closing Date and all payments thereafter shall be made from
such plan as provided in the plan.

9.04. No Transfer of Assets

      Neither Seller nor its Related Persons will make any transfer of pension
or other employee benefit plan assets to Buyers.

                              10. Confidentiality

10.01. Restricted Use of Confidential Information

      (a) Each Receiving Party acknowledges the confidential and proprietary
nature of the Confidential Information of the Disclosing Party and agrees that
such Confidential Information (i) shall be kept confidential by the Receiving
Party; (ii) shall not be used for any reason or purpose other than to evaluate
and consummate the Contemplated Transactions; and (iii) without limiting the
foregoing, shall not be disclosed by the Receiving Party to any Person, except
in each case as otherwise expressly permitted by the terms of this Agreement or
with the prior written consent of an authorized representative of Seller with
respect to Confidential Information of Seller (a "Seller Contact") or an
authorized representative of Buyers with respect to Confidential Information of
Buyers (a "Buyers Contact"). A Receiving Party shall disclose the Confidential
Information of a Disclosing Party only to the Receiving Party's Representatives
who require such material for the purpose of evaluating the Contemplated
Transactions and are informed by the Receiving Party of the obligations of this
Section 10 with respect to such information. Each Receiving Party shall (A)
enforce the terms of this Section 10 as to its respective Representatives; (B)
take such action to the extent necessary to cause its Representatives to comply
with the terms and conditions of this Section 10; and (C) be responsible and
liable for any breach of the provisions of this Section 10 by it or its
Representatives.

      (b) Unless and until this Agreement is terminated, Seller shall maintain
as confidential any Confidential Information of Seller relating to any of the
Assets or the Assumed Liabilities, including for this purpose any information of
Seller of the type referred to in Sections 1.01(g)(i), (ii), and (iii), whether
or not disclosed to Buyers. Notwithstanding the preceding sentence, Seller may
use any Confidential Information of Seller before the Closing in the Ordinary
Course of Business in connection with the transactions permitted by Section
7.02.

      (c) From and after the Closing, the provisions of Section 10.01(a) shall
not apply to or restrict in any manner Buyers' use of any Confidential
Information of Seller relating to any of the Assets or the Assumed Liabilities.

10.02. Exceptions

      Section 10.01(a) and 10.01(b) do not apply to that part of the
Confidential Information of a Disclosing Party that a Receiving Party
demonstrates (a) was, is or becomes generally available to the public other than
as a result of a breach of this Section 10 or the Confidentiality Agreement by
the Receiving Party or its Representatives; was or is developed by the Receiving
Party independently of and without reference to any Confidential Information of
the Disclosing Party; or was, is or becomes available to the Receiving Party on
a nonconfidential basis from a Third Party not bound by a confidentiality
agreement or any legal, fiduciary or other obligation restricting disclosure.
Seller shall not disclose any Confidential Information of Seller relating to any
of the Assets or the Assumed Liabilities in reliance on the exceptions in
clauses (b) or (c) above.

10.03. Trade Secrets

      Any trade secrets of a Disclosing Party shall also be entitled to all of
the protections and benefits under applicable trade secret law and any other
applicable law. If any information that a Disclosing Party deems to be a trade
secret is found by a court of competent jurisdiction not to be a trade secret
for purposes of this Section 10, such information shall still be considered
Confidential Information of that Disclosing Party for purposes of this Section
10 to the extent included within the definition set forth in Section 1.01(g). In
the case of trade secrets, each Receiving Party hereby waives any requirement
that the Disclosing Party submit proof of the economic value of any trade secret
or post a bond or other security.

10.04. Legal Proceedings

      If a Receiving Party becomes compelled in any Proceeding or is requested
by a Governmental Authority having regulatory jurisdiction over the Contemplated
Transactions to make any disclosure that is prohibited or


--------------------------------------------------------------------------------
                                       38
<PAGE>

otherwise constrained by this Section 10, that Receiving Party shall provide the
Disclosing Party with prompt notice of such compulsion or request so that it may
seek an appropriate protective order or other appropriate remedy or waive
compliance with the provisions of this Section 10. In the absence of a
protective order or other remedy, the Receiving Party may disclose that portion
(and only that portion) of the Confidential Information of the Disclosing Party
that, based upon advice of the Receiving Party's counsel, the Receiving Party is
legally compelled to disclose or that has been requested by such Governmental
Authority; provided, however, that the Receiving Party shall use reasonable
efforts to obtain reliable assurance that confidential treatment will be
accorded by any Person to whom any Confidential Information is so disclosed. The
provisions of this Section 10.04 do not apply to any Proceedings between the
parties to this Agreement.

10.05. Return or Destruction of Confidential Information

      If this Agreement is terminated, each Receiving Party (a) shall destroy
all Confidential Information of the Disclosing Party prepared or generated by
the Receiving Party without retaining a copy of any such material; (b) promptly
shall deliver to the Disclosing Party all other Confidential Information of the
Disclosing Party, together with all copies thereof, in the possession, custody
or control of the Receiving Party or, alternatively, with the written consent of
a Seller Contact or a Buyers Contact (whichever represents the Disclosing Party)
destroy all such Confidential Information; and (c) shall certify all such
destruction in writing to the Disclosing Party; provided, however, that the
Receiving Party may retain a list that contains general descriptions of the
information it has returned or destroyed to facilitate the resolution of any
controversies after the Disclosing Party's Confidential Information is returned.

10.06. Attorney-Client Privilege

      The Disclosing Party is not waiving, and will not be deemed to have waived
or diminished, any of its attorney work product protections, attorney-client
privileges or similar protections and privileges as a result of disclosing its
Confidential Information (including Confidential Information related to pending
or threatened litigation) to the Receiving Party, regardless of whether the
Disclosing Party has asserted, or is or may be entitled to assert, such
privileges and protections. The parties (a) share a common legal and commercial
interest in all of the Disclosing Party's Confidential Information that is
subject to such privileges and protections; (b) are or may become joint
defendants in Proceedings to which the Disclosing Party's Confidential
Information covered by such protections and privileges relates; (c) intend that
such privileges and protections remain intact should either party become subject
to any actual or threatened Proceeding to which the Disclosing Party's
Confidential Information covered by such protections and privileges relates; and
(d) intend that after the Closing the Receiving Party shall have the right to
assert such protections and privileges. No Receiving Party shall admit, claim or
contend, in Proceedings involving either party or otherwise, that any Disclosing
Party waived any of its attorney work-product protections, attorney-client
privileges or similar protections and privileges with respect to any
information, documents or other material not disclosed to a Receiving Party due
to the Disclosing Party disclosing its Confidential Information (including
Confidential Information related to pending or threatened litigation) to the
Receiving Party.

                            11. Additional Covenants

11.01. Payment of All Taxes Resulting From Sale of Assets by Seller

      Seller shall pay in a timely manner all Taxes resulting from or payable in
connection with the sale of the Assets pursuant to this Agreement, regardless of
the Person on whom such Taxes are imposed by Laws. Under no circumstances shall
this Section 11.01 be interpreted to (a) obligate Seller to pay the income Taxes
of any Shareholder or (b) create any rights, as a third party beneficiary or
otherwise, in favor of any Person other than Buyers or Seller.

11.02. Payment of Other Retained Liabilities

      In addition to payment of Taxes pursuant to Section 11.01, Seller shall

<PAGE>

11.03. Removing Excluded Assets

      Seller shall use its Best Efforts to remove, on or before the Closing
Date, all Excluded Assets from all Facilities and other Real Property to be
occupied by Buyers. Such removal shall be done in such manner as to avoid any
damage to the Facilities and other properties to be occupied by Buyers and any
disruption of the business operations to be conducted by Buyers after the
Closing. Any damage to the Assets or to the Facilities resulting from such
removal shall be paid by Seller at the Closing. Should Seller fail to remove the
Excluded Assets as required by this Section, Buyers shall have the right, but
not the obligation, (a) to remove the Excluded Assets at Seller's sole cost and
expense; or (b) to store the Excluded Assets and to charge Seller all storage
costs associated therewith. Seller promptly shall reimburse Buyers for all costs
and expenses incurred by Buyers in connection with any Excluded Assets not
removed by Seller on or before the Closing Date. No breach of this Section 11.03
shall be deemed a Breach of this Agreement.

the Assets, to and including the Effective Time.

circumstance, condition, conduct, event, fact, failure to act, incident,
occurrence, plan, practice, situation, status or transaction on or before the
Closing Date involving Seller or its business. CTI shall reimburse Seller for
all out-of-pocket expenses and reasonable attorneys' fees incurred in providing
such cooperation.

11.06. Customer and Other Business Relationships

      After the Closing, Seller will cooperate with Buyers in its efforts to
continue and maintain for the benefit of Buyers those business relationships of
Seller existing prior to the Closing and relating to the business to be operated
by Buyers after the Closing, including relationships with lessors, employees,
regulatory authorities, licensors, customers, suppliers and others, and Seller
will satisfy the Retained Liabilities in a manner that is not detrimental to any
of such relationships. Seller will refer to Buyers all inquiries relating to
such business. Seller shall not, and shall use its Best Efforts to be sure that
none of its officers, employees, agents or shareholders shall, take any action
that would tend to diminish the value of the Assets after the Closing or that
would interfere with the business of Buyers to be engaged in after the Closing,
including disparaging the name or business of Buyers.

11.07. Retention of and Access To Records

      After the Closing Date, Buyers shall retain for a period consistent with
Buyers' record-retention policies and practices those Records of Seller
delivered to Buyers. Seller shall have the right to retain copies of any and all
such Records for all legitimate purposes of Seller, including preparation of
financial statements and tax returns. Buyers also shall provide Seller and its
Representatives reasonable access thereto, during normal business hours and on
at least three days' prior written notice, to enable them to prepare financial
statements or tax returns or deal with tax audits. After the Closing Date,
Seller shall provide Buyers and its Representatives reasonable access to Records
that are Excluded Assets, during normal business hours and on at least three
days' prior written notice, for any reasonable business purpose specified by
Buyers in such notice. Prior to the destruction of any Records of Seller
delivered to Buyers, CTI shall notify Seller of such proposed destruction and
shall offer Seller the option, exercisable within 30 days after Seller's receipt
of such notice, to retake possession and ownership of any such Records.

11.08. Restrictions on Seller Dissolutions or Distributions

      Seller shall not dissolve, or make any distribution of the proceeds
received pursuant to this Agreement, until Seller's payment, or adequate
provision for the payment, of all of its obligations pursuant to Sections 11.01


--------------------------------------------------------------------------------
                                       40
<PAGE>

and 11.02. As used in this Section 11.08, "adequate provision for payment" shall
include any agreement by one or more Shareholders to assume and agree to pay,
discharge, and satisfy such obligations as they become due.

obligations of CTI to make the Earnout Payments pursuant to Section 3.03 of this
Agreement.

11.10. Financial Covenants Relating to Sub

this Agreement (without giving effect to any supplement to any Seller's
Schedule), (ii) the Schedules hereto, any supplements to any Schedules, (iv) the

suspected to be present on or before the Closing Date on or at the Facilities

Assets at any time on or prior to the Closing Date.

      (b) Buyers will be entitled to control any Remedial Action, any Proceeding
relating to an Environmental Claim and, except as provided in the following
sentence, any other Proceeding with respect to which indemnity may be sought

12.05. Right of Setoff

      (a) Upon notice to Seller specifying in reasonable detail the basis
therefor, Buyers may set off any amount to which they may be entitled under this
Section 12 in respect of any Damages arising from or in connection with any
Retained Liabilities (other than the Retained Liabilities described in Section
2.04(a)) against any Earnout Payments otherwise payable pursuant to Section
3.03; provided, however, that:

            (i) Buyers shall have no right to set off under this Section
12.05(a) until the total of all Damages with respect to such matters exceeds
Five Hundred Thousand and No/100 Dollars ($500,000.00);

            (ii) In the event that the $500,000 threshold for set off described
in Section 12.05(a)(i) is reached, then in such event Buyers may set off any
amounts to which they may be entitled under this Section 12 against any Earnout
Payments, from the first dollar of such Damages and without regard to the
foregoing $500,000 threshold; and

            (iii) Buyers shall have no right to set off under this Section
12.05(a) in respect of any individual Damage and all Damages in the aggregate in
excess of Three Million and No/100 Dollars ($3,000,000.00).

      (b) Upon notice to Seller specifying in reasonable detail the basis
therefore, Buyers may set off any amount to which they may be entitled under
this Section 12 in respect of any Damages arising from or in connection with
Retained Liabilities described in Section 2.04(a) against any Earnout Payments
otherwise payable pursuant to Section 3.03, and the limitations of Section

to such Retained Liabilities.


--------------------------------------------------------------------------------
                                       43
<PAGE>

      (c) The provisions of this Section 12.05 shall limit neither Buyers'
rights under Sections 12.02 and 12.03 to obtain indemnification and
reimbursement from Seller on behalf of the Buyer Indemnified Parties, nor
Seller's obligations with respect to such indemnification and reimbursement.

      (d) The exercise of Buyers' rights of setoff under this Section 12.05 by
Buyers in good faith, whether or not ultimately determined to be justified,
shall not constitute an event of default under this Agreement and shall not
constitute an election of remedies or limit Buyers in any manner in the
enforcement of any other remedies that may be available to them.

12.06. Third-Party Claims

      (a) Promptly after receipt by a Person entitled to indemnity under
Sections 12.02, 12.03 (to the extent provided in the last sentence of Section
12.03), or 12.04 (an "Indemnified Person") of notice of the assertion of a
Third-Party Claim against it, the Indemnified Person shall give notice to the
Person obligated to indemnify under such Section (an "Indemnifying Person") of
the assertion of such Third-Party Claim; provided, that the failure to notify
the Indemnifying Person will not relieve the Indemnifying Person of any
liability that it may have to any Indemnified Person, except to the extent that
the Indemnifying Person demonstrates that the defense of such Third-Party Claim
is prejudiced by the Indemnified Person's failure to give such notice.

      (b) If an Indemnified Person gives notice to the Indemnifying Person
pursuant to Section 12.06(a) of the assertion of a Third-Party Claim, the
Indemnifying Person shall be entitled to participate in the defense of such
Third-Party Claim and to assume the defense of such Third-Party Claim with
counsel satisfactory to the Indemnified Person to the extent that it wishes,
unless (i) the Indemnifying Person is also a Person against whom the Third-Party
Claim is made and the Indemnified Person determines in good faith that joint
representation would be inappropriate or (ii) the Indemnifying Person fails to
provide reasonable assurance to the Indemnified Person of its financial capacity
to defend such Third-Party Claim and provide indemnification with respect to
such Third-Party Claim. After notice from the Indemnifying Person to the
Indemnified Person of its election to assume the defense of such Third-Party
Claim, so long as the Indemnifying Person diligently conducts such defense, it
shall not be liable to the Indemnified Person under this Section 12 for any fees
of other counsel or any other expenses with respect to the defense of such
Third-Party Claim, in each case subsequently incurred by the Indemnified Person
in connection with the defense of such Third-Party Claim, other than reasonable
costs of investigation. If the Indemnifying Person assumes the defense of a
Third-Party Claim, (A) such assumption will conclusively establish for purposes
of this Agreement that the claims made in that Third-Party Claim are within the
scope of and subject to indemnification, and (B) no compromise or settlement of
such Third-Party Claims may be effected by the Indemnifying Person without the
Indemnified Person's Consent unless (I) there is no finding or admission of any
violation of Law or any violation of the rights of any Person; (II) the sole
relief provided is monetary damages that are paid in full by the Indemnifying
Person; and (III) the Indemnified Person shall have no liability with respect to
any compromise or settlement of such Third-Party Claims effected without its
Consent. If notice is given to an Indemnifying Person of the assertion of any
Third-Party Claim and the Indemnifying Person does not, within 10 days after the
Indemnified Person's notice is given, give notice to the Indemnified Person of
its election to assume the defense of such Third-Party Claim, the Indemnifying
Person will be bound by any determination made in such Third-Party Claim or any
compromise or settlement effected by the Indemnified Person.

      (c) Notwithstanding the foregoing, if an Indemnified Person determines in
good faith that there is a reasonable probability that a Third-Party Claim may
adversely affect it or its Related Persons other than as a result of monetary
damages for which it would be entitled to indemnification under this Agreement,
the Indemnified Person may, by notice to the Indemnifying Person, assume the
exclusive right to defend, compromise or settle such Third-Party Claim, but the
Indemnifying Person will not be bound by any determination of any Third-Party
Claim so defended for the purposes of this Agreement or any compromise or
settlement effected without its Consent (which may not be unreasonably
withheld).

      (d) Notwithstanding the provisions of Section 14.04(b), Seller hereby
consents to the nonexclusive jurisdiction of any court in which a Proceeding in
respect of a Third-Party Claim is brought against any Buyers Indemnified Person
for purposes of any claim that a Buyers Indemnified Person may have under this
Agreement


--------------------------------------------------------------------------------
                                       44
<PAGE>

with respect to such Proceeding or the matters alleged therein and agree that
process may be served on Seller with respect to such a claim anywhere in the
world.

      (e) With respect to any Third-Party Claim subject to indemnification under
this Section 12: (i) both the Indemnified Person and the Indemnifying Person, as
the case may be, shall keep the other Person fully informed of the status of
such Third-Party Claim and any related Proceedings at all stages thereof where
such Person is not represented by its own counsel; and (ii) the parties agree
(each at its own expense) to render to each other such assistance as they
reasonably may require of each other and to cooperate in good faith with each
other in order to ensure the proper and adequate defense of any Third-Party
Claim.

      (f) With respect to any Third-Party Claim subject to indemnification under
this Section 12, the parties agree to cooperate in such a manner as to preserve
in full (to the extent possible) the confidentiality of all Confidential
Information and the attorney-client and work-product privileges. In connection
therewith, each party agrees that: (i) it will use its Best Efforts, in respect
of any Third-Party Claim in which it has assumed or participated in the defense,
to avoid production of Confidential Information (consistent with applicable law
and rules of procedure), and (ii) all communications between any party hereto
and counsel responsible for or participating in the defense of any Third-Party
Claim shall, to the extent possible, be made so as to preserve any applicable
attorney-client or work-product privilege.

12.07. Other Claims

      A claim for indemnification for any matter not involving a Third-Party
Claim may be asserted by notice to the party from whom indemnification is sought
and shall be paid promptly after such notice.

12.08. Indemnification in Case of Strict Liability or Indemnitee Negligence

      SUBJECT TO THE EXPRESS PROVISIONS OF THIS AGREEMENT, THE INDEMNIFICATION
PROVISIONS IN THIS SECTION 12 SHALL BE ENFORCEABLE REGARDLESS OF WHETHER THE
LIABILITY IS BASED UPON PAST, PRESENT OR FUTURE ACTS, CLAIMS OR LEGAL
REQUIREMENTS (INCLUDING ANY PAST, PRESENT OR FUTURE BULK SALES LAW,
ENVIRONMENTAL LAW, FRAUDULENT TRANSFER ACT, OCCUPATIONAL SAFETY AND HEALTH LAW
OR PRODUCTS LIABILITY, SECURITIES OR OTHER LEGAL REQUIREMENT) AND REGARDLESS OF
WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION IS SOUGHT)
ALLEGES OR PROVES THE SOLE, CONCURRENT, CONTRIBUTORY OR COMPARATIVE NEGLIGENCE
OF THE PERSON SEEKING INDEMNIFICATION OR THE SOLE OR CONCURRENT STRICT LIABILITY
IMPOSED UPON THE PERSON SEEKING INDEMNIFICATION.

                                13. Termination

13.01. Termination Events

      By notice given prior to or at the Closing, subject to Section 13.02, this
Agreement may be terminated:

      (a) by CTI, if a material Breach of any provision of this Agreement has
been committed by Seller and such Breach has not been cured by Seller within a
reasonable time after notice of such material Breach has been given to Seller or
waived by Buyers;

      (b) by Seller, if a material Breach of any provision of this Agreement has
been committed by Buyers and such Breach has not been cured by Buyers within a
reasonable time after notice of such material Breach has been given to CTI or
waived by Seller;

      (c) by CTI, if any condition in Section 4.03 has not been satisfied as of
the date specified for Closing in Section 4.01 or if satisfaction of such a
condition by such date is or becomes impossible other than through the failure
of CTI to comply with its obligations under this Agreement, and CTI has not
waived such condition on or before such date;


--------------------------------------------------------------------------------
                                       45
<PAGE>

      (d) by Seller if any condition in Section 4.04 has not been satisfied as
of the date specified for Closing in Section 4.01 or if satisfaction of such a
condition by such date is or becomes impossible other than through the failure
of Seller to comply with its obligations under this Agreement, and Seller has
not waived such condition on or before such date;

      (e) by mutual consent of Buyers and Seller;

      (f) by CTI if the Closing has not occurred on or before June 30, 2004 or
such later date as the parties may agree upon, unless CTI is in material Breach
of this Agreement; or

      (g) by Seller if the Closing has not occurred on or before June 30, 2004
or such later date as the parties may agree upon, unless Seller is in material
Breach of this Agreement.

13.02. Effect of Termination

      Each party's right of termination under Section 13.01 is in addition to
any other rights it may have under this Agreement or otherwise, and the exercise
of such right of termination will not be an election of remedies. If this
Agreement is terminated pursuant to Section 13.01, all obligations of the
parties under this Agreement will terminate, except that the obligations of the
parties in this Section 13.02 and Section 10 and 14 (except for those in Section
14.05) will survive; provided, however, that if this Agreement is terminated
because of a Breach of this Agreement by the nonterminating party or because one
or more of the conditions to the terminating party's obligations under this
Agreement is not satisfied as a result of the party's failure to comply with its
obligations under this Agreement, the terminating party's right to pursue all
legal remedies will survive such termination unimpaired.

                             14. General Provisions

14.01. Expenses

      Except as otherwise provided in this Agreement, each party to this
Agreement will bear its respective fees and expenses incurred in connection with
the preparation, negotiation, and execution of this Agreement and the other
Transaction Documents and performance of the Contemplated Transactions,
including all fees and expense of its Representatives and the Seller Acquisition
Fee described in Section 5.26 ("Transaction Costs"); provided, however, that all
Transaction Costs paid by Seller prior to the Closing Date shall be deducted at
Closing from the Purchase Price pursuant to Section 4.02(b)(i); and provided
further, that in the event that this Agreement is terminated prior to the
Closing by CTI pursuant to Section 13.01, other than by reason of a material
Breach of this Agreement by Seller, then CTI shall reimburse Seller for that
portion of its Transaction Costs that consists of reasonable accounting fees and
reasonable fees and expenses incurred by Seller for the Intellectual Property
Audit. Buyers will pay one-half and Seller will pay one-half of the HSR Act
filing fee, if any. If this Agreement is terminated, the obligation of each
party to pay its own fees and expenses will be subject to any rights of such
party arising from a Breach of this Agreement by another party.

14.02. Public Announcements

      Any public announcement, press release or similar publicity with respect
to this Agreement or the Contemplated Transactions will be issued, if at all, at
such time and in such manner as Buyers determines. Seller shall use its Best
Efforts to ensure that, except with the prior consent of Buyers or as permitted
by this Agreement, neither Seller nor any of its Representatives shall disclose
to any Person (a) the fact that any Confidential Information of Seller has been
disclosed to Buyers or its Representatives, that Buyers or its Representatives

be informed of the Contemplated Transactions, and Buyers will have the right to

internal laws of the State of Tennessee as applied to contracts made and
performed within the State of Tennessee, without regard to the principles
thereof regarding resolution of conflicts of law

      (b) Buyers and Seller hereby (i) submit to the jurisdiction of any state

United States District Court for the Eastern District of Tennessee sitting at
Knoxville in any action or proceeding arising out of or relating to this
Agreement or the Contemplated Transactions; (ii) agree that all claims in
respect of the action or proceeding may be heard and determined in any such
court; (iii) agree not to bring any action or proceeding arising out of or
relating to this Agreement or the Contemplated Transactions in any other court;
(iv) waive any defense of inconvenient forum to the maintenance of any action or

14.05. Enforcement of Agreement

      Each party acknowledges and agrees that the others would be irreparably
damaged if any of the provisions of this Agreement are not performed in

--------------------------------------------------------------------------------
                                       47
<PAGE>

any party could not be adequately compensated in all cases by monetary damages
alone. Accordingly, in addition to any other right or remedy to which any party
may be entitled, at law or in equity, it shall be entitled to enforce any
provision of this Agreement by a decree of specific performance and to
temporary, preliminary and permanent injunctive relief to prevent Breaches or
threatened Breaches of any of the provisions of this Agreement, without posting
any bond or other undertaking.

14.06. Waiver; Remedies Cumulative

      The rights and remedies of the parties to this Agreement are cumulative
and not alternative. Neither any failure nor any delay by any party in
exercising any right, power or privilege under this Agreement or any of the
documents referred to in this Agreement will operate as a waiver of such right,
power or privilege, and no single or partial exercise of any such right, power
or privilege will preclude any other or further exercise of such right, power or
privilege or the exercise of any other right, power or privilege. To the maximum
extent permitted by applicable law, (a) no claim or right arising out of this
Agreement or any of the documents referred to in this Agreement can be
discharged by one party, in whole or in part, by a waiver or renunciation of the
claim or right unless in writing signed by the other party; (b) no waiver that
